Serial No. 332,692.

This invention relates to mounting for the picking spindle of a loom and it is'the general object of the invention to provide means for varying the position of the spindle relatively to the shuttle box of the loom.

In some forms of weft replenishing looms the shuttle is actuated by a picker which slides along a spindle or picker rod mounted behind the shuttle. The picker stick is located behind the shuttle also so as to provide a clear path for the passageof an exhausted bobbin at the time of transfer. The picker spindle is ordinarily substantially parallel to the reed, but due to slight deformation of the lay especially at the box end, the spindle will occasionally change its proper relation with respect to the reed so as to cause the picker to move in an improper path. l t is an important object of our present invention to provide means for adjusting the outer end of the spindle so that the same may be kept in correct alignment with the reed.

It is a more specific object of our present invention to provide a holder for the picker spindle through which the latter extends freely, the holder being adjusted toward and from the shuttle box and being capable of limited vertical adjustment.

With these and other objects in view which will appear as the description proceeds, our invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.

Inthe accompanying drawing wherein a convenient embodiment of our invention is set forth, I,

Fig. 1' is a top plan view of aloomhaving our invention applied thereto, certain parts being removed for the sake of clearness,

Fig. 2 is a rear elevation taken in the direction of arrow 2, Fig. 1, and

Fig. 3 is an enlarged vertical section on line 33 of Fig. 2. v c

Referring particularly to Figs. 1 and 2 we have shown the loom lay L having a shuttle box 10 in which is mounted a shuttle S. The lay is provided with the lay end 11 having ears 12 to receive lay driving mechanism not shown. The lay end is provided with a boss 13 which receives the inner end of a picker spindle P. A. check nut 1a mounted on the threaded end 15 of the picker spindle may serve to hold the picker spindle in fixed relation with respect to the boss, said picker spindle being threaded into the latter. The reed indicated at R in Fig. l is as usual positioned to engage the rear wall of the shuttle S and the latter is guided by the upright wall 16 of the box 10.

The picker stick 17 may be actuated in the usual manner and passes through a slot 18 in a picker 19 which is slidable on the rod P, having its forward end 20 in engagement with the outer end of the shuttle S. As the picker moves along the red the shuttle is expelled from the box to move along the reed R. The matter thus far described is of common construction and is found not only on the drop box end of fancy looms, but also on the magazine end of certain weft replenishing looms.

Our invention relates more particularly to the means for adjusting the outer right hand end as viewed in Fig. 1 of the picker spindle P, and in carrying our invention into effect as shown more particularly in Fig. 3 we provide a carrier 30 preferably of cylindrical form as suggested in Fig. 1 and drill therethrough a hole 31 of proper size to receive the outer end of the picker spindle. The hole is not quite centrally located along the length of the carrier 30, but as shown herein is a little nearer the bottom than the top of said carrier for a purpose to be described hereinafter. The upper end of the carrier has a threaded hole 32 extending axially therethrough to receive a screw 33 having a head 34. The screw extends lar to eye 35. Said eye member 11 is provided with threaded shank 42 extendin into a threaded hole 42' in the lay end an held tightly with respect to the latter by a check nut 43.

If desired we may employ a bracing screw 44 which is threaded into the carrier 80 and has a head 45 to engage the lay end 11. This screw 44 is held in position by a lock mt t and my lie opposite the spindle P nsmhown in Fig. 3.

Under normal conditions the carrier 3.0 will be clamped against the eye members and 41 by the upper and lower screws '88-and 39, respectively, thus holding said carrier in fixed position with respect to the "lay, the distance of the outer end of the picker spindle -P from the box back 1:6 being deter mined by the position of the screws 36 and 42 with respect to the lay end 11. If during the course of the operation of the loom it should be found that the .outerend of the picker spindle moves too far forwardly, the screws 34 and may be removed and the merrier 30 taken from between the eye members 35 and 41, after which the latter may be rotated .to move rearwardly with respect ito-the .layend the PIOPBldlStBDCQ. The carrier may then be inserted between the eyes and thescrews 33 and 39 be :replaced, =a corresponding adjustment being made on screw 44 so that the latter will serve to :brace the central part of the carrier with respect to the lagy .end. The q osite adjustment of course mnyihe .made ii it is found that the picker spindle is too far to the rear of its proper position.

Should it be desired to efiecta slight vertical adjustment of the outer end of the mod LP .the holder 30 may he invented. The auflustment will The reflected dueto the previously described relation between .the ends of the carrier .and the hole 31, namely, that said .hole is not exactly in the longitudinal icenterof the carrier.

From the foregoing we have novided a sim le form of mount- .ing .for t e outercnd o the picker spindle, and mounting providing means for adjust- .the osition of the picker spindle toward and from the box back. It will also .be seen that the-screw 4.4 acts as a brace to -steltdythe carrier 30 with respect to the lay and. It will furthermore be seen that .by inverting the carrier a slight vertical adjustment'ofthe'hole 31 may be effected.

Having thus described .our invention it will be seen that changes and modifications may 'he made therein 'by those skilled 'in the \art \without departing .from the spirit and scope of the invention and we do .not :wishto be limited .to the detailsIherein-ldisclosed, but what we claim :is:

1. In a'loomllay having a pickers 'indle the forward end of which ispositione with respect to the lay, a carrier for .the outer it will be .seen that end of the spindle through which the latter extends, a pair of screw members located one above and the other below the spindle and threaded into the lay, and connection between the screw members and the carrier to hold the latter in fixed posision with respect to the lay.

2. In a loom lay having a picker s indle the fiorumllmd of which is cued with respect to the lay, a (miner ihmring ww- :M himceimefileispindle, a screw threaded into each end of the carrier, one screw being above and the other below the spindle, and a threaded member to cooperate with each screw and held to the camier and having threaded engagement with the lay.

3.. In a loom lay having a ,picker indle the forwardend of which is positione with resfectto the lay, a canrier for the outer on of .the spindle throu h which the spindle extends, a ,pair of spacedscrew eye members threaded mto and adjustable with respect .to the 'lay, and means extending through the screw eyes :and into and in holding an gagement with the carrier to hold the atter :1 with mspect to the screw eye members.

In testimony whereof we have hereunto afiixed our signatures.
